Step by step
Binance asks for your number at Account → Security → SMS Authentication (or phone sign-up). Expect a 6-digit code; it can arrive by SMS.
Get your Japan number
Sign up at PhoneBorn with an email, top up with crypto and choose Japan: a monthly plan ($12.60) if you want to keep the account, or a single-use Binance OTP number ($2.62) for one code.
Open Binance
Go to Account → Security → SMS Authentication (or phone sign-up).
Enter the +81 number
Select Japan (+81) in the country picker and paste the number from your dashboard without a leading 0. Japan mobiles look like 090 xxxx xxxx → +81 90 xxxx xxxx.
Enter the 6-digit SMS code plus your existing verification (email/authenticator)

Day-to-day life in Japan runs on LINE, X and Instagram, yet Binance remains the app for a stable 2FA number for a crypto account. A +81 number keeps that account tied to the country without using your personal SIM.
Selling and buying on Mercari: Resellers and collectors trading anime goods, cameras or vintage fashion on Japanese marketplaces use a +81 number for account verification.
Losing an exchange 2FA number can freeze withdrawals until a lengthy reset.
Japan runs on LINE, and many domestic services, from PayPay to Mercari, ask for a Japanese mobile number during sign-up. Because tourists usually cannot get a voice SIM, a +81 number is a practical option for learners, collectors and people planning a move.
Local context
Voice SIM contracts in Japan generally require a residence card, so short-term visitors usually only get data-only SIMs or eSIMs. A Japan number from PhoneBorn needs no SIM and no ID — only an email.
